“…First of all, compared to the supine position, passive warming is harder to work in lateral position and lithotomy position with less contact area to the operation bed, less sheets or surgical draping and higher heat dissipation. Furthermore, lithotomy position is susceptible to hypothermia because baroreceptor loading augments perioperative hypothermia in anesthetised and paralysed subjects by reducing the body temperature threshold for peripheral vasoconstriction (Edgcombe et al, 2008; Seo et al, 2018).…”

Background: Hypothermia is a common clinical issue during the perioperative period.The patients with perioperative inadvertent hypothermia are associated with higher risk of postoperative complications and higher hospitalisation costs. Aims:The aim of this study is to explore the prevalence of and predictors for hypothermia in patients entering postanaesthesia care unit. Design: Retrospective cohort study.Methods: A rigorous retrospective cohort study was conducted according to the STROBE reporting checklist. A total of 7216 patients were enrolled in this study. The perioperative variables potentially related to hypothermia were collected. Univariate analysis and multivariate logistic regression analysis were performed to investigate the contributing factors. Results:The overall prevalence of inadvertent hypothermia in postanaesthesia care unit was 21.3% (n = 1505). The multivariate logistic regression analysis showed that

Background: Despite improved medical treatment strategies, postoperative pain, nausea, and vomiting remain major challenges. This systematic review investigated the relationship between perioperative respiratory and hemodynamic interventions and postoperative pain, nausea, and vomiting. Methods: PubMed and Embase were searched on March 8, 2021 for randomized clinical trials investigating the effect of perioperative respiratory or hemodynamic interventions in adults undergoing non-cardiac surgery. Investigators reviewed trials for relevance, extracted data, and assessed risk of bias. Meta-analyses were performed when feasible. GRADE was used to assess the certainty of the evidence.Results: This review included 65 original trials; of these 48% had pain, nausea, and/or vomiting as the primary focus. No reduction of postoperative pain was found in meta-analyses when comparing recruitment maneuvers with no recruitment, high (80%) to low (30%) fraction of oxygen, low (5-7 ml/kg) to high (9-12 ml/kg) tidal volume, or goal-directed hemodynamic therapy to standard care.

“…Apart from applying active heating methods in patients, the effectiveness of anesthesia in preventing hypothermia is a research topic [17, 18]. In a study comparing lung-protective ventilation and conventional high tidal volume ventilation, lung-protective ventilation did not have an advantage in maintaining the patient’s core temperature [19].…”

Introduction: Low-flow anesthesia (LFA) reduces the fresh gas flow (FGF) entering the anesthesia circuit and saves on the volatile agent used. In this study, the effect of LFA with sevoflurane on core temperature and the incidence of perioperative hypothermia were investigated. Methods: According to the FGF applied, patients were classified into three groups: LFA (1 L/min), medium-flow anesthesia (MFA = 2 L/min), and high-flow anesthesia (HFA = 4 L/min). Patients’ demographic data and the initial (T1) and final (T2) core temperatures during the operation were compared. Results: A total of 160 patients were included in the study. The T2 value of the HFA group was significantly lower than the LFA group (p = 0.028). Different flow values were found to have a significant effect on temperature change (F = 21.630, p < 0.001, partial eta squared = 0.216). There was a significant difference between the mean temperatures measured at two different times (F = 301.064, p < 0.001, partial eta squared = 0.657). The overall incidence of hypothermia was 32.5%, with 52 patients. Hypothermia (T2<36°C) incidences were not different between the LFA group and the MFA and HFA groups (p = 0.682). However, perioperative core temperature loss was significantly lower in the LFA group (p = 0.001). Conclusions: LFA using sevoflurane was not sufficient alone to significantly reduce the incidence of hypothermia. However, we have demonstrated that it may also have a beneficial effect on reducing perioperative temperature loss.
